Assumption: You live in the US.

The first 3, and possibly also the last 2 pieces look like custom made and are likely not of general use to the typical home chemist.

More importanly, I would wonder how the possesion of these pieces is going to shake out in court, no matter what their inherent value. That is, will you be "opening a can of worms" for yourself. It may be best for you to just write them off as a loss and not mention them. I'm sure you are not naieve in regard to US society's general outlook on scary chemical glassware. This will all be double trouble for you if you happen to be unfortunate enough to live in the great state of Texas.

#1 and #2 look like Kontes (could be Ace glass... too blurry to tell) continuous solvent repurification heads. I'd put an estimated value of approx $500-700 replacement value on thems.

Even though this is chemglass, it should be similar in price:

I have no clue what #3-4 is. I'd guess its some kind of fractionating stillhead.

evil_lurker thanks! you picked the right ones, they are most definetley what you mentioned. sorry about hte lousy pics everyone.

yes i am a little nervous about the judge. i mentioned to the da that im a biochem student (True) and that they were to be sold on ebay, not for personal use. i live in CA not in texas (thank god).

Though you must remember, California is known for its chemical paranoia (perhaps not as glass fearing as the wonderful state of Texas though...)

#3,4 and 5 are pictures of a spinning band column with a dividing head attached (this is used for controlling the reflux ratio). These are quite expensive (maybe 1000 or more).

I do believe you have some antiques from Dr Frankenstein's laboratory.
They look like film props for the mad scientist! No idea!
